Losing green card after 6 years of no entry to USA

[xortilio]

My dad had a green card and he hasn't entered the US in 6 years since mid 2014. He had his mom pass away in early 2015 after being sick and his dad also pass away in 2027 also after being sick. He was taking care of them and he couldn't travel to the US. After that he also had other as important family events until early 2020. My question is:
Is it worth it for him to try and re-enter the US or not even bother after 6 years? did he for sure lost his residency? He can have proof of all the events that kept him from traveling (doctor testimonies, death certificates,and so on...). I appreciate any help.

6 yrs is too long. I would not bother entering the US.
I would restart the immigrant visa process

There is the option of applying for a returning resident visa. https://travel.state.gov/content/tra...-resident.html
